Figure 9-2.
The osi_posedge signal pulses on each rising edge of the prescaled clock. This signal is not
directly accessible by the CPU, but can be used to trigger the input capture function of
Timer/Counter0. Using OSI in combination with the input capture function of Timer/Counter0
facilitates accurate measurement of the oscillator frequencies with a minimum of CPU calcula-
tion. Refer to
Capture function.
